摘要： A Gram-negative, moderately halophilic, strictly aerobic strain, designated YIM 95345(T), was isolated from a soil sample of a hypersaline mine in Yunnan province, PR China, and subjected to a polyphasic taxonomic study. Strain YIM 95345(T) grew at 15-45 degrees C (optimum 30-35 degrees C), 3.0-23.0% (w/v) NaCl (optimum 10.0-11.0%, w/v) and pH 6.0-9.0 (optimum pH 7.0-8.0). Phylogenetic analyses based on 16S rRNA gene sequences revealed that the organism belongs to the genus Aquisalimonas and exhibited sequence similarity of 96.6% to the sole type strain Aquisalimonas asiatica CG12(T). The predominant isoprenoid quinone was Q-8 and the major fatty acids were C-16:0, C-19:0 cyclo omega 8c and C-18:1 omega 7c. The polar lipids consisted of diphosphatidylglycerol, phosphatidylcholine, phosphatidylethanolamine, phosphatidylglycerol, phosphatidylinositol, three aminolipids and three unidentified phospholipids. The G+C content of the genomic DNA was 59.4 mol%. Based on the results of our comparative phylogenetic, chemotaxonomic and physiological analyses, the new isolate is assigned to a novel species of the genus Aquisalimonas, for which the name Aquisalimonas halophila sp. nov. is proposed, with the type strain YIM 95345(T) (=DSM 25902(T)=CCTCC AB 2012043(T)).
